those software calculators are utter BS. go run my PC through that same software, and tell me the result. i'll show you the results from my wall meter showing how inaccurate it is.
you have to remember that the sensor reading your 12V rail isnt direcnt connected to the PSU like a multimeter would be - its part of the motherboard, and a few steps in. so while it may record drops, we dont know how precise it is (can it read changes from 12.70 to 12.71, or is it moving in steps of 0.03 or the like) - and because of its placement, its reading only one part of the motherboard. hell we dont even know if the software needs to be calibrated to be accurate on the motherboard, so you may get accurate movement but the readings are off by a few percent.
i'm not saying your voltage drops are irrelevant - it is a sign of the PSU reaching its load... but thats likely just due to it being a crap PSU, and not the wattage. a quality PSU matters more than the (often exaggerated) wattage output.
Your right. I did my research. This kingwin MKX-850 is the best bang for your buck 850 available. It supplies equal amperage on the 12v rail than other brands like corsair. It's rated on the 12V rail @ 840W which calculates to 70 amps. Compared to say CORSAIR CMPSU-850TX which is also rated at 70A on 12V rail. It costs 129.99. The kingwin was 99.99. it's a Modular power supply. the non modular version supplies 68A i believe but is only 79.00 i think. Kingwin is a great value/ performance brand.
I want to agree with you about AIDA64's power current readings for the cpu and gpu. I've seen them both hit 60A a piece under 100% peak load. That's 120A! That's not possible, right? It's rated at 70A, but could be pushed to say 80-90 max. What do you think?
